Definitions

  • the invention relates to a fan wheel for a circulating radial fan of a cooking chamber or the like, with a number of radially arranged blades which project substantially parallel to the axis of rotation of the fan wheel from a support disk facing a housing wall of the cooking chamber.
  • Circulating radial blowers are often used in cooking areas of commercial kitchen appliances or the like, which serve to even out the atmosphere inside the cooking space when treating items to be cooked in the cooking space, such as solid dishes.
  • the cooking chamber atmosphere often has particulate constituents, such as in particular fat particles, which are to be separated as quickly as possible from the cooking chamber atmosphere while the circulation radial fan is running.
  • the invention has for its object to ensure a reliable separation of fat particles or condensate from the cooking chamber atmosphere in a structurally simple manner and without providing additional condensate separating devices.
  • this object is achieved in that at least between some of the blades near the support disk, but at a distance from this guide plates are arranged, the radially outer outer edge of which is substantially aligned with the outer circumference of the fan wheel, the radially inner inner edge of which is spaced from the axis of rotation of the fan wheel lies and which each form a nozzle device for generating a radially outward gas flow near the support disk with the support disk and the respectively adjacent two blades.
  • the guide plates are provided between all pairs of blades.
  • the radial side edges of the guide plates are attached to the respectively adjacent two blades.
  • the guide plates are formed inclined from their inner edge to their outer edge in the direction of the support disk.
  • the invention is based on the surprising finding that it is possible to drain condensate from the cooking space of commercial kitchen appliances or the like, using a circulating radial fan dispose reliably by creating nozzle devices near the support disk of the fan wheel by means of the guide plates provided according to the invention, which generate such a radially outward flow that fat particles or the like, which are in the cooking chamber atmosphere, when deflecting from the axial direction of flight, with respect the axis of rotation of the fan wheel, impinge in the direction of the nozzle devices on the support disks or are guided radially outward through the nozzle devices onto deflector plates or the like.
  • the condensate particles, particles and the like can easily be supplied to separating devices, such as a condensate drain opening.
  • the fan wheel according to the invention has, in the exemplary embodiment shown there, a number of radial blades 10 which project substantially parallel to an axis of rotation 12 of the fan wheel from a support disk 14 which, after the fan wheel has been installed, into the circulation -Radial blower of a cooking space of a commercial kitchen appliance of a housing wall facing the cooking space, which is penetrated by a drive shaft of the fan wheel.
  • the blades 10 are welded to the support disk 14.
  • the blades 10 of the fan wheel are welded to a support ring 16.
  • Baffles 18 are arranged between the individual blades 12 and are welded to the respectively adjacent blades 10.
  • the radially inner inner edge of the guide plates 18 is arranged at a distance from the axis of rotation 12 of the fan wheel, while the radially outer outer edge of the guide plates 18 is essentially aligned with the outer circumference of the fan wheel.
  • the guide plates 18 are formed inclined from their inner edge to their outer edge in the direction of the support disk 14, as can be seen in particular from FIG. 2, so that a nozzle-like cross section is produced which points radially outward from the axis of rotation 12 to the circumference of the fan wheel.
  • the guide plates 18 provided according to the invention have the effect that a radially outward flow is generated near the support disk 14 of the fan wheel, which leads to the fact that grease or moisture particles or the like, which separate from the cooking space volume on the support disk 14, radially through the between the support disk 14 and the respective guide plate 18 nozzle are conveyed to the outside, where they can be easily removed to a drain opening or the like via corresponding deflector plates or the like.
  • the support plate 14, the support ring 16, the blades 10 and the baffles 18 are made of sheet metal in the embodiment shown. Instead, it could also be readily provided that one or more of these elements are made of plastic or the like.
